The present study was designed with an aim to observe the effect of increasing urbanization and traffic activity on the physiology of a foliose lichen, Phaeophyscia hispidula (Ach.) Essl., collected from 13 different localities, growing in their natural habitat, in Pauri and Srinagar, two cities in the Himalayas. Six parameters i.e., Chl. a, Chl. b, total pigment, chlorophyll degradation, carotenoid and total protein content, proved the most useful to assess air pollution, were measured. Chlorophyll content and protein content are an efficient parameter to measure the air quality of a region. The study indicates that P. hispidula is pollution tolerant (adaptation) and able to withstand local emissions from vehicle exhausts. 相似文献

Emissions from landfills via leachate and gas are influenced by state and stability of the organic matter in the solid waste
and the environmental conditions within the landfill. This paper describes a modified, ecologically sound waste treatment
technique, where municipal solid waste is anaerobically treated in a lysimeter-scale landfill bioreactor with leachate recirculation
to enhance organic degradation. The results demonstrate a substantial decrease in organic matter (BOD 99%, COD 88% and TOC
81%) and a clear decrease in nutrient concentrations especially ammonia (85%) over a period of 1 year with leachate recirculation. 相似文献

India has reasons to be concerned about climate change. Over 650 million people depend on climate-sensitive sectors, such
as rain-fed agriculture and forestry, for livelihood and over 973 million people are exposed to vector borne malarial parasites.
Projection of climatic factors indicates a wider exposure to malaria for the Indian population in the future. If precautionary
measures are not taken and development processes are not managed properly some developmental activities, such as hydro-electric
dams and irrigation canal systems, may also exacerbate breeding grounds for malaria. This article integrates climate change
and developmental variables in articulating a framework for integrated impact assessment and adaptation responses, with malaria
incidence in India as a case study. The climate change variables include temperature, rainfall, humidity, extreme events,
and other secondary variables. Development variables are income levels, institutional mechanisms to implement preventive measures,
infrastructure development that could promote malarial breeding grounds, and other policies. The case study indicates that
sustainable development variables may sometimes reduce the adverse impacts on the system due to climate change alone, while
it may sometimes also exacerbate these impacts if the development variables are not managed well and therefore they produce
a negative impact on the system. The study concludes that well crafted and well managed developmental policies could result
in enhanced resilience of communities and systems, and lower health impacts due to climate change. 相似文献

Considerable research indicates that a wide range of socio-economic factors influence attitudes and perceptions about environmental
hazards and risks, and that social trust in those who manage a hazard is strongly correlated to judgements about risks and
benefits. We suggest that there are three steps that lead to environmental risk perceptions: acquisition of information, interpretation
and synthesis of different pieces of information, and understanding of that information in light of previous knowledge, perceptions,
or attitudes. In this study we presented 211 college students in the sciences and non-sciences with ecological and exposure
information using text, tables and maps to examine the factors that affect information acquisition and interpretation concerning
ecological issues at a fictitious hazardous waste site. Students were allowed about an hour to read the materials and answer
questions. The percent of students answering each question correctly varied from 4 to 82%, indicating that some questions
were extremely difficult to answer. We attributed these differences to variations in the number of places information was
presented (in text, tables, maps, or a combination) and the complexity of the information (how many pieces of information
were required to answer the question correctly). The correlation between the number of students answering each question correctly
and these combined measures (frequency, complexity) was −0.72. Thus, although there were differences in accuracy concerning
ecological information as presented in this study, the major differences were accounted for by how the information was presented,
and how much information was required. This suggests that risk communicators should carefully determine which ecological information
is critical for the target audience, and ensure that it is presented several times (in different forms). That a lower percentage
of people correctly answered questions that required synthesizing several pieces of information suggests that this complexity
should be reduced where possible, or that the pieces of information should be tied clearly to the conclusion. Self-declaration
of effort and perceptions of safety of the site did not markedly influence the relationship between accuracy, difficulty of
finding information, and complexity of information. Other possible confounding variables (i.e., science vs non-science major)
only accounted for about 27% of the variation in student’s overall score on ecological questions; age, ethnicity, and gender
did not enter as significant variables. We cannot manage environmental hazards with appropriate stakeholder input unless we
understand how to present environmental information to achieve a full understanding. Protection of human health and the environment
requires that people understand ecological and exposure information, particularly on buffer lands. 相似文献

Relatively little is known about exposures to traffic-related particulate matter at schools located in dense urban areas. The purpose of this study was to examine the influences of diesel traffic proximity and intensity on ambient concentrations of fine particulate matter (PM2.5) and black carbon (BC), an indicator of diesel exhaust particles, at New York City (NYC) high schools. Outdoor PM2.5 and BC were monitored continuously for 4–6 weeks at each of 3 NYC schools and 1 suburban school located 40 km upwind of the city. Traffic count data were obtained using an automated traffic counter or video camera. BC concentrations were 2–3 fold higher at urban schools compared with the suburban school, and among the 3 urban schools, BC concentrations were higher at schools located adjacent to highways. PM2.5 concentrations were significantly higher at urban schools than at the suburban school, but concentrations did not vary significantly among urban schools. Both hourly average counts of trucks and buses and meteorological factors such as wind direction, wind speed, and humidity were significantly associated with hourly average ambient BC and PM2.5 concentrations in multivariate regression models. An increase of 443 trucks/buses per hour was associated with a 0.62 μg/m3 increase in hourly average BC at an NYC school located adjacent to a major interstate highway. Car traffic counts were not associated with BC. The results suggest that local diesel vehicle traffic may be important sources of airborne fine particles in dense urban areas and consequently may contribute to local variations in PM2.5 concentrations. In urban areas with higher levels of diesel traffic, local, neighborhood-scale monitoring of pollutants such as BC, which compared to PM2.5, is a more specific indicator of diesel exhaust particles, may more accurately represent population exposures. 相似文献

Studies were conducted on the spatial distribution of different stages of the mango stone weevil, Sternochetus mangiferae (Fabr.) at Hessaraghatta farm of the Indian Institute of Horticultural Research, Bangalore, during 1983. The values of various parameters of distribution showed that the eggs are distributed as a negative binomial (contagious) distribution, whereas larvae and adults follow a positive binomial (random) distribution. It is suggested that the change in distribution may be due to the lower population densities in larval and adult stages. 相似文献

India has good reasons to be concerned about climate change as it could adversely affect the achievement of vital national development goals related to socio‐economic development, human welfare, health, energy availability and use, and infrastructure. The paper attempts to develop a framework for integrated impact assessment and adaptation responses, using a recently built railroad coastal infrastructure asset in India as an example. The framework links climate change variables — temperature, rainfall, sea level rise, extreme events, and other secondary variables — and sustainable development variables — technology, institutions, economic, and other policies. The study indicates that sustainable development variables generally reduce the adverse impacts on the system due to climate change alone, except when they are inadequately applied. The paper concludes that development is a vital variable for integrated impact assessment. Well crafted developmental policies could result in a less‐GHG intensive future, enhanced adaptive capacities of communities and systems, and lower impacts due to climate change. 相似文献
